Specification of Letters Patent.

Patented Aug. 22, 1916.

To all whom it may concern: I

- Be it known that 1, CHARLES A. LUND- earn, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Adding and Listing Machines, of which the following is a specification.

The present invention relates to so-called tally-roll equipments for adding and listing machines and is in the nature of an improvement upon the prior invention of Fred F. Main which has been made the subject of prior Patent 1,173,293, issued February'29, 1916. As in the case of Mains said invention I propose to have the tally roll come into printing position automatically as an incident to the taking of totals, and also to provide for its use at any time at the will of the user of the machine. My improvements pertain to the characterv of means employed for driving the tally-roll carriage back to normal or non-printing position and to the character of means for controlling the positioning of the tally-roll carriage for printing purposes. I aim to provide means of a more positive character and capable of more compact and unobtrusive arrangement than heretofore for applying power to restore the tally-roll carriage to non-printing position; and as to control in positioning for printing I aim to provide for such positioning as a preliminary to operation of the machine proper, and I furthermore aim to provide for indefinitely maintaining the tally-roll carriage in printing position as well" as for indefinitely maintaining it in non-printing position. In addition to this I provide for establishing two different printing positions for the purpose of distinguishing between imprints of items or amounts and imprints of totals or sub-totals on thetally strip in case the conditions are such as to preclude the printing upon the strip of the usual sign to distinguish totals and sub-totals.

With these and incidental objects in view the invention consists in certain novel features of construction and combination of parts, the essential elements whereof are recited in the appended claims and a preferred form of embodiment of which is illustrated in the accompanying drawings forming part of this specification.

In said drawings, Figure 1 represents in left side elevation an adding and listing machine of the well-known Burroughs type having applied thereto a tally-roll equipment which embodies my present invention; Fig. 2 is a broken rear elevation of said machine showing the tally roll in non-printing position; Fig. 3 is a rear elevation minus the main paper carriage and with the tallyroll carriage in printing position; Fig. 4 is a vertical section on the line H of Fig. 3; Fig. 5 is a right side elevation of parts appearing in rear elevation at the lower left hand corner of Fig. 3; Fig. 6 is a sectional and somewhat fragmentary plan view taken substantially on line66 of Fig. 3; Fig. 7 is a detail sectional plan View on the order of the right-hand portion of Fig. 6 but illustratin a slightly different condition; Fig. 8 is a fragmentary sectional rear elevation representing normal conditions; Fig. 9 is a sectional left side elevation of certain parts which appear normal in Fig. 1, whereas in this present figure the total key is shown almost fully depressed; Fig. 10 is a similar view with the special tally -key depressed; Fig. 11 shows an example of work.

The adding and listing machine proper is so well known through disclosures of prior patents and commercial usage as to require no special description, though reference will be made to some familiar parts with which those introduced for carrying out my present invention directly cooperate.

The back panel of the machine casing is designated by the numeral 2 and there is fastened to it as usual a track 3 for the laterally shifting main paper carriage 4. 'The usual cradle 5 is mounted upon this carriage and supports the roller platen 6. Said cradle is here shown with a holder 7 for sheet paper such, for example, as ledger sheets witli which the tally roll equipment is especially desirable. This equipment oomprises an upper roll holder 8 and a lower roll holder 9 connected by a thin metal plate 10 which runs through the narrow space between the carriage track 3 and the panel 2.

A chute 11 is arranged at the upper part ofthis plate and the tally strip is threaded through this chute and thence through an opening 12 in the plate 10 (Fig. 4) so as to run close to the paper overlying the roller platen 6. Just below this another chute 13 is formed upon the plate to envelop the feed lever 122 does not affect it.

tally strip where it passes between the carriage track and the back panel of the machine casing.

The type plates 618 of the machine proper strike through the opening 12 to reach the roller platen and the paper overlying the same, and, when the tally roll is in printing position, the tally strip itself which is car boniZed on the rear side so that the imprint made upon it will be duplicated upon the sheet paper. The tally, strip runs down out of the chute 13 under a guide roller 14 and over a table 15 to the under side of a takeup roller 16 in the lower roll holder 9,- a pressure roller 17 being suitably arranged below said take-up roller 16 so that the strip may be fed by the turning of the latter. This is accomplished through the medium of. a ratchet 18 on said take-up roller and a pawl 19 carried by an arm 20 having a laterally projecting stud 21 arranged to be operated upon. by the familiar feed lever v122 of the machine proper when the tally roll is moved over into printing position. Normally this stud 21 stands off to the left as the parts appear in Fig. 2, so that said It will of course be understood that there should be no feed of the tally strip except when it is in printing position or in connection with the printing upon the strip.

The above described tally roll holder is carried upon a rod 30 being secured thereto by set screws 31 in bosses on the side plates of the lower roll holder 9. The rod 30 is conveniently arranged to slide through the lugs 32 on the base of the" machine and the lugs 33 on the back panel of the machine which lugs constitute parts of hinges by which said back panel is mounted on said base. The rod takes the place of the usual pintles and it will be noted that this arrangement makes for compactness and the minimum of projection of the tally roll structure from the rear of the machine. A

means will ordinarily serve to normally respring 40 connecting one of the set screws 31 with a screw stud in one of the lugs 33 tends to pull the whole tally roll carriage to the right as the parts are seen in Figs. 2 and 3 and thus move it into printing position.

Referring to the feature of my present invention firstmentioned in the opening statement of this specification to wit, the character of means for driving the tally roll carriage back to non-printing position, which strain the spring, I mount a. pivot screw stud 50 in the back panel 2 (Figs. 2 and 3) and suspend from it a lever 51 which operates upon a roller stud 52 carried by a collar 53 which is secured to the slide rod 30. On

I the same stud 50 I mount a bell crank lever which has a short laterally extending arm '54 having a gear segment 55, which meshes with a short rack 56 formed upon or secured to the upper part of the vertically sliding line-space plate 89 which is itself a familiar element of these machines. The aforesaid feed lever 122 is coupled to said plate as usual so that the latter is reciprocated in every operation of the machine. Therefore the said bell crank lever is oscillated in every operation of the machine. It has a longer depending arm 57 which extends illustrated in Fig. 2, the plate 89 being elevated andlthe lower arm of the bell crank consequently swung over to the left as the parts are there seen and the lever 51 correspondingly swung so that it holds the tally roll carriage in non-printing position. It will be seen that if the pawl 58 is disengaged from. the stud 51 the restraint imposed upon the tally roll carriage by the lever 51 will be removed, and the spring' lO will be permitted to pull the tally roll carriage into printing position unless otherwise restrained as by the latch hereinafter described. Fig. 3 illustrates the effect of disengaging the pawl and unlatching the carriage, the latter having been pulled to printing position by its spring and having correspondingly swung the lever 51 over to the right as the parts are seen in this figure of the drawing. Upon operation of the machine the bell crank 5457 will be rocked and the pawl reengaged with the stud 51 so that in the last half cycle of operation of the machine the lever 51 will be. forcibly swung back to the left and will restore the tally roll carriage to non-printing position.

It willbe seen that the above described mechanism for applying power to restore the tally roll carriage is compact and unobtrusive lying close against the back panel of the machine and is direct and positive in its operation. Furthermore, it will be noted that, in line with the second stated object of my present invention, the separable connection between the bell crank and the restoring lever provides for the shifting of the tally roll carriage into printing position as a preliminary to the operation of the machine proper.

Referring next to the means for bringing the tally roll into action at will, a lever 70 (Fig.- 1) is pivoted at its middle on a frame stud 2 and its rear arm extends under the pawl 58 which is elongated into a tapered finger 58 with a suitable curvature of its under edge to provide for its riding ,over the top edge of the lever 70 in ordinary operations of the machine without any resultant disengagement of the pawl from the stud 51 and also for theriding of the stud 51 along its under edge. The forwardly extending arm of the lever 70 is coupled to a link 71 which extends up to the front part of the machine and is there coupled to the stem 72 of a key 73 at the lower left hand corner of the keyboard. This stem is bifurcated at its lower end to engage a aiding frame stud 2 and is permitted su cient oscillation to engage its notch 74 under the upper keyboard plate when it is desiredv to keep the key down. Depression of this key will obviously rock the lever 70 and elevate the pawl 58 disengaging it from the stud 51 Depression of said key also effects an unlatching of the tally roll carriage. A latch plate 75 is hung from the rear end of said lever and guided at its lower end in the slot of a collar 78 surrounding the rod 30 and carried by a bushing 79 (Fig. 5) having a drive fit through the adjacent lugs 33. Normally a forward portion of the latch plate above a horizontal shoulder 75 thereof (Figs. 1, 8 and 9) occupies a notch 30 in the upper side of said rod at the right hand end thereof as the parts are viewed in Figs. 7 and 8, thereby holding the rod against movement by its spring 40. Depression of the key 73 results in lifting the latch plate (Fig. 10) and freeing the rod so that it and the tally roll carriage may be shifted over until a leather washer 80 adjacent the collar 53 strikes as a stop shoulder against one of the lugs 32, as shown in Fig. 6 and also in F ig. 3. This fixes the printing position of the tally roll carriage for items or amounts, and it will be obvious that the tally roll carriage may be kept in its printing position indefinitely by latching down the key 7 3 or holding it down, for in such case the pawl 58 remains uncoupled from the lever 51 so that the bell crank 54 57 will oscillate idly.

' Referring next to the bringing into action of the tally roll as an incident to the taking of a total or sub-total, the reference numeral 265 designates the familiar total key, and

the reference numeral 265 the familiar sub-total key, depression of either of which effects a rearward movement of the familiar link 226 which performs its customary function of operating a release bail for restoring any depressed amount keys 291 of the machine proper. I utilize this link 226 for effecting release of the tally roll carriage. 'It is slightly modified by making a depression 226 in the under side of its slot, the

60 purpose of which depression will presently ap ear.

mount a V-shaped stud 90 in the link 226 for cooperation with the Y-shaped upper extremity of a lever 91 which is pivoted 6 intermediate its ends upon a frame stud 2,

as shown in Figs. 1, 9 and 10. A spring 92 holds the upper arm of this lever normally forward and against a stop stud 93. The lower arm of the lever terminates in a for- Wardly extending cam linger 91 which is designed to cooperate with a stud on the rear arm of the lever 70. Rearward swinging of the upper arm of the lever 91 and corresponding forward swinging of the lower arm causes the upper edge of said finger to act upon the stud 70 with a camming effect and lift the rear arm of the lever 70. The upper extremity of the lever 91 normally stands in rear of the V-shaped lug 90 as shown in Fig. 1 so that depression of total or sub-total key will effect such rocking of the lever 91.. The effect is to disengage the pawl 58 from the lever 51, as in the case of depression of the key 73, and to also raise the latch plate 7 5. However, the movement is not so extensive as that produced by depression of the key 73, (compare Figs. 9 and 10) the purpose being to bring about a slightly different printing position of the tally roll strip in order that the imprint of a total or sub-total thereon may be distinguished from that of an item or amount by a slight difference in lateral position on the strip. A special construction of the latch plate comes into consider-- ation here and also a special construction of the slide rod 30. The latter is flattened along its rear side at the right hand end (Fig. 6) leading up to a shoulder 30 so located as to determine the lateral position of the rod and the tally roll carriage differently from that determined by abutment of the aforesaid leather washer against the lug 33. This is illustrated in Fig. '2' which represents the condition resulting from depression of total or sub-total key. In this connection a portion of the latch plate 75 serves as a stop for the tally roll carriage, to wit, a depending portion 75 which passes down to the rear of the rod 30.

A forward vertical edge 75 of this downward extension fits close to the flattened rear surface of the rod 30 and the portion of the latch plate adjacent this edge serves as an abutment for the shoulder 30 to encounter when the latch plate is lifted by the total or sub-total key. When lifted by the tally key 7 3 this portion of thelatch plate is raised entirely above the rod (Fig." 10) so that the latter and the tally roll carriage may move farther over or until the leather washer 80 comes up against the lug 33. For the purpose of properly confining the latch plate in its up-and-down movements a keeper plate 92 is fastened to the collar 78 and formed with a bent-over ear 92 extending in rearof the downward extension 75" of the latch plate which extension is sufficiently elongated to remain en gaged with said ear when the latch plate is n te raised to its highest extent. This lowermost.

portion of the latch plate is out back from the abutment portion adjacent the vertical"- would necessarily be an occasional performs ance requiring theinterposition ofthe tally strip for the one operation andv its immediate restoration to non-printing position the lever 91 is not held'displaced throughout the depression of total or sub-total key, it being understood that in all of these ma chines having the construction here shown.

these keys remain down throughout the operation of the machine. Now it is essential in the present construction, in order that the tally roll shall be restored to non-printing position, that the pawl 58 reengage the stud 5l 'at the conclusion of the first half cycle of operation of the machine. Therefore the before-mentioned V-shaped stud 90 on the link 226 is so related to the upper extremity of the lever that said stud may wipe past the point of the lever and permit the latter to be restored. The arcuate movements of the lever and the link 226 provide for the escape of the lug 90 past the point of the lever. As the parts appear in Fig. 9 this is just about to occur with completion of depression of the total key. Of course upon the freeing of this lever its lower arm swings back and releases the lever 70. A spring 99 is applied to the forward arm of the latter to insure its prompt return to or toward normal and upon such release of said lever its rear arm drops and the pawl 58 bears down upon the stud 51 ready to immediately engage the same when the bell crank 5 15Z reaches the limit of its initial swing upon operation of the machine. Likewise the latch plate 75 lowers upon the rod 30 so that when the lever 51 is restored by the said bell crank in the last half cycle of the operation of the machine proper, the tally roll carriage will become latched in its non-printing position. At the conclusion of the operation the total keys are restored and the stud 9O rides over the point of the lever 91 and drops in front of it, this being permitted by the beforementioned slight depression 226 in the under side of the slot of the link. To insure the repositioning of the said stud in front of the lever a spring 100 is applied to the link 226 tending to pull it down.

The distinguishing of totals or sub-totals from items or amounts by diflerent lateral positions on the tally strip (see example of work Fig. 11) is of consequence under condi tions such as may exist and would make the usual special printing of signs to distinguish total and sub-totals unavailable. For example, in a machine of large keyboard capacity, such as is now commonly employed and in which one or more splits or subdivisions of the recording inechanism were provlded for and atthe same time a narrow tally strip wasin use, the imprint of a total amount to the left of a split or subdivision would be separated by a. considerable spacefrom the imprint ofthe special sign at the extreme right and the tally strip mightnot be wide enough to take the sign imprint. Where both items-and totals are printed on a tally strip it is i desirable that they be readily distinguishable andthe abovedescribed arrangement provides for this even in cases where the customary sign printing cannot be relied upon,a total or sub-total being printed slightly out of line with items or a little to the-left, as the total 421264; ap-

pears in Fig. '11.

It is desirable that the machine he available for use without the tally roll equipment and therefore I'.provide; for keeping the latter indefinitely out of commission at the will of the operator. To this end I provide a notch 30 near the left hand end of the rod 30 as the parts are viewed in Fig. 3, and arrange a latch 105to engage said notch as illustrated in Fig. 2. This latch is pivoted upon a plate 106 which is secured to a collar 107 on a bushing '108 having a drive fit in the adjacent lug 33. A spring 110 is applied to this latch so that it will cross the pivot thereof and thus serve either for bold ing it in effective position or--i'n the ineffective positionsillustrated in Fig. 5 against a stud 111 to which one end of the sprin llO-is applied. v
